2,5,5-trimethylhexan-1-ol

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-(2H-Benzotriazol-2-yl)-6-chloromethyl-4-methyl-phenol (7.0 g, 25.6 mmol) is partly solved in dioxane (190 mL) at 80° C. 2,5,5-Trimethyl-hexan-1-ol (124.1 g, 731 mmol) and sodium hydride (1.7 g, 42 mmol, 60% in mineral oil) are added subsequently. The orange reaction mixture is stirred at 80° C. for one hour and evaporated to dryness. The residue is dissolved in ethyl acetate and extracted with water. The organic layer is dried over sodium sulphate, filtered and evaporated to dryness. The crude product is purified by column chromatography (ethyl acetate/heptane 1:12) to yield 4.8 g of 2-(2H-Benzotriazol-2-yl)-6-(2,5,5-trimethylhexyloxymethyl)-4-methyl-phenol. evaporated to dryness The residue is dissolved in ethyl acetate extracted with water The organic layer is dried over sodium sulphate filtered evaporated to dryness The crude product is purified by column chromatography (ethyl acetate/heptane 1:12)
